New York (CNN) - A self-described "ex-madam" who claims she supplied fellow city comptroller candidate Eliot Spitzer with escorts several years ago is facing charges of illegally distributing prescription drugs, authorities said.

Kristin Davis, 38, was arrested on Monday night and charged with selling Adderall, Xanax and other drugs. She's also accused of orchestrating the sale of approximately 180 oxycodone pills for cash.
